Item type:Publication, Decomposing total power flows into contributions originating from power sources in loads, generators, and network elements(Elsevier BV, 2024-08); Rajičić, DragoslavTo thoroughly analyze the conditions in power lines, transformers or loads, it is essential to have knowledge of their active and reactive power flow contributions from each power source. Understanding these contributions allows for a detailed analysis of the impact of active and reactive power flow contribution from each power source on active and reactive power losses in each network element, as well as the determination of power participation of each source to every load. This paper provides the necessary equations and an adequate procedure for calculating power flow contributions. The method is suitable for meshed network and considers shunt elements, avoiding problematic simplifications. Furthermore, it ensures impartiality towards any network user, making it well-suited for application in deregulated environments. By offering valuable information useful , this method supports the creation of transparent and non-discriminatory agreements between network operator and users. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Parametric Analysis of Conductive Coupling of Transmission Line Tower Grounding and Pipeline in Multilayer Soil(Wydawnictwo SIGMA-NOT, sp. z.o.o., 2023-07-28); ;Grcev, Leonid ;Gjorgievski, Vladimir ;Velkovski, BodanMarkovska Dimitrovska, MarijaFaults in electric power system may give rise of coating stress voltages on nearby pipelines due to mutual electromagnetic coupling. To prevent hazardous situations, accurate modelling of the electromagnetic interactions between such systems is required. In this paper, we perform parametric analysis of the effects of multilayer soil and of the effectiveness of different mitigation techniques in reducing coating stress voltages on a short pipeline section due to conductive coupling. Analyses are performed using full-wave electromagnetic model, based on the method of moments. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Assessment of Human Exposure to Electric and Magnetic Fields Near Transmission Lines Using FEMM(University of Maribor, Faculty of Energy Technology, 2023-06) ;Glushica, Bojan; ; Arnautovski-Toseva, VesnaThe intensity of ELF electric and magnetic fields near transmission lines is of particular interest in environmental and equipment protection studies. The use of numerical tools is the most efficient method for their assessment. In this paper, we numerically compute the electric and magnetic fields near different configurations of high-voltage transmission lines using the open- source software FEMM 4.2. Computed fields are compared with reference levels related to human exposure to electromagnetic fields. The accuracy of the applied method is validated with published, numerically computed and measured results. - Some of the metrics are blocked by yourconsent settings
